ULTRABASE PA SAND FINISH
ULTRABASE PA (Sand finish) is a high-performance pre-applied HDPE membrane designed for waterproofing of foundations, tunnels, and other engineering structures. The material represents composite sheets of thick HDPE membrane with a special pressure sensitive adhesive compound protected with sand that reacts with a wet mortar and gives an excellent integral bonding. The waterproofing membrane bonds directly to the concrete, thus sealing it and preventing any ingress of water around the structure, even in cases of soil sedimentation.
AREA OF APPLICATION:
Pre-applied HDPE membrane ULTRABASE PA (Sand finish) is used for waterproofing of foundations, tunnels, underground parts of buildings and structures in pre-applied systems with liquid concrete pouring on top of the material.
ADVANTAGES:
- Highly reactive adhesive along with sand ensures complete and reliable adhesion to the concrete surface.
- Exceptional dimensional stability, puncture, and tear resistance.
- The membrane does not require protection before backfilling.
- Can be used as a barrier to water, moisture, and gas.
- Versatile area of application.
- Suitable for different soil conditions.
- Weather and UV resistant.
- Strong resistance to industrial chemicals.
- Trafficable during reinforcement during pouring of concrete.
